SECTION-BEAM HEAD.

Lasarte.

To all lwhom z't may concern:

Be it known that I, RAY THORNTON, a citizen of the United States, and resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Section-Beam Heads, of which the following is a specification. 4

My invention relates to section-beams, used for storing and transporting warp and filling, and more particularly to the construction of the flanges or heads of such beams.

The heads of section beams in .most general use,`are made of cast iron, and weigh aboutifty pounds apiece, thereby greatly increasing the weight of the structure and the cost of shipping the same. It is a matter of common experience that ,such cast iron beam heads are frequently broken because, in order to reduce their weight, they are made of minimum thickness, and also that unless great care is taken in the storage and shipping of such beams, the metallic heads cut into and injure the wooden barrels of the beams.

The object of the present invention is to provide a unitary or one-piece beam head that will not be subject to these defects and limitations, and that will be very much lighter in weight than a metal head without sacrificing the strength required for devices of this character.

I attain this object by making the beam head of cross-banded wood as hereinafter more fully set forth, and while I am aware that wooden beam heads have heretofore been proposed, experience has shown that they have not proven satisfactory in prac-v tice, and that they' have never gone into commercial use.

My invention will be described by a reference to-the drawings which accompany and forma part of this specification and which illustrate a type of wooden beam head which has proven t0 be a satisfactory. and practical substitute for the metallic heads of the prior art.

In the drawings l Figure 1 is a longitudinal central section ofmy improved section-beam, taken on the line 1-1 of Fig. 2;

' resents the barrel made up, as usual, ofv a number of slats secured to .the disks 11 fwhich in turn, are mounted on the shaft 12 by the set screws 13 or other appropriate means. 4It is to be understood, however, that my improved beam head or flange may be used with any type of section-beam.

The beam heads are each formed of a plurality of layers of wood preferably three in num er as shown, and each layer consists of a plurality of bands herein shown as three in number. The outer bands 14, 14, 14, and 15, 15', 15, are united at their meeting edges preferably by dovetailing, and are vsecured to the inner bands 16, 16', 16 by gluing under pressure in the usual wellknown manner, or in any other suitable way. To strengthen the structure, the rivets 17 may also be employed. For the bands, I prefer to use rock maple or other tough resilient wood, although I do not limit myself to any particular kind of wood. Preferably, the bands of one layer have a different direction from those of the other or others, and as shown in Fig. 2, the inner bands are arranged at right angles to the outer bands. The dovetailed joints between the bands of one of the outer layers are preferably out of line with the joints of the other outer layer. The beam head is provided with a rim 18 grooved to receive the restraining cord employed when the thread is being unwound, and preferably said rim is so constructed as to clamp the outer edges of the several layers for the purpose of bind- This may be accomplished by making the cross section of the outer edge of the head arc-shaped, and clampingF the rim on said outer edge by means o a cold tire setting machine, the jaw of which is shown at 19, in Fig. 4. The metallic rim 18 not only binds the layers t0- gether at their outer edges but protects the edge of the beam-head from abrasion and prevents moisture from entering the wood through the pores in the edge. It will be understood, however that other means may be employed for bin ing the layers together at their outer edges, and that if a metallic rim be used for this purpose it need not be arc-shaped as shown and may be suitably shaped to perform this function.

The head or flange is applied to the beam i?) the usual manner by means of nuts 2O t readed to the shaft, and bearin against the washers 21 secured to the hea thereby forcing the head against thebarrel and the shoulder 22l of said shaft.

It has been practically demonstrated that beam heads constructed as above set forth, are very much lighter than the metallic heads now in common use, and thatthey possess such great resiliency that it is practically impossible to break them, while at the same time, they can be made much more cheaply than cast iron heads. It has been demonstrated also that said beam heads in addition to being of much lighter weight than the metallic heads of the prior art, can be perfectly balanced, which, when they are used as loom beams, results in securing an even tension in the winding of ne yarns or war s and also in preventing the beam from having the uneven movement known as jumping ahead, to which metallic loom beams are commonly subject, such uneven movement resulting in making bad spotsin the cloth.

It will be understood that various modiications may be made in the device herein specifically described, and illustrated, without departing from the true scope of my invention.

Having thus described one illustrative embodiment of my invention without, however, limiting the same thereto, what I claim and desire to secure by Letters Patent, is

1. The combination with a section-beam, of a unitary or one-piece head comprising in its construction a plurality of layers of wood, each layer having a plurality of bands permanently united at their meeting edges, the cross-'section of the outer edge of said head being arc-shaped, and a metallic rim clamped on said outer edge of said head and binding said layers together.

2. The combination with a section-beam,

of a unitary or one-piece head comprising inits construction a plurality of layers of wood, each layer having a plurality of bands permanently united at their meeting edges, the bands of one layer having a different direction from those of the other or others, the cross-section of the outer edge of said head being arc-shaped, and a metallic rim clamped on said outer edge of said head and binding said layers together.

3. The combination .with a section-beam, of a unitary or one-piece head comprising in its construction a plurality of layers of Wood, each layer having a plurality of bands permanently united at their meeting edges, the joints between the bands of one of the outer layers being out of line with'the joints of the other outer layer and the cross-section of the outer edge of said head being arcshaped, and a metallic rim clamped on said outer edge of said head and binding said layers together.

4. The combination With a section-beam, of a unitary or one-piece head comprising in its construction a plurality of layers of Wood, each layer having a plurality of bands permanently united at their meeting edges the bands of one layer having a different direction from those ofthe other or others, the joints between the bands of one of the outer layers being out of line with the joints of the other outer layer and the cross-section of the outer edge of said head being arcshaped, and the metallic ring clamped on said outer edge of said head and binding said layers together.

5. The combination with a section-beam, of a unitary or one-piece head comprising in its construction a plurality of layers of wood, each layer having a plurality of bands permanently united at their meeting edges, 'the bands of the inner layer being at right angles to those of the outer layers, the

joints between the bands of one of the outer layers being out of line with the joints of the other outer layer, and a metallic rim clamped on the outer edge of said head, said rim being so shaped as to bind said layers together.

6. The combination with a section-beam, of a unitary or one-piece head comprising in its construction a plurality of layers of wood, each layer having a plurality of bands permanently united at their meeting edges, and a metallic rim clamped on the outer edge of said head, said rim being so shaped as to bind said layers together.

7. The combination with a section-beam, of a unitary or one-piece head comprising in its construction a plurality of layers of wood, each layer having a plurality of bands permanently ,united at their meeting edges, the bands of one layer having a different direction from those of the other or others, and a metallic rim clamped on the outer edge of said head, said rim being so shaped as to bind said layers together.
